-Wpointer-sign catches all these cases across the codebase that should be using gdb_byte for raw target bytes. I think these are all obvious, hence I've collapsed into a single patch. gdb/ 2013-04-19 Pedro Alves <palves@redhat.com> * aarch64-tdep.c (aarch64_default_breakpoint): Change type to gdb_byte[].
